IMPROVEMENT lN LAMPS.

Specification forming part of Letters Patent No. 204,608, dated June 4, 1878; application filed February 9, 1878.

To all whom it may concern:

Be it known that I, FREDERICK RATGLIFF, of West Meriden, in the county of N ew Haven and State of Connecticut, have invented a new and valuable Improvement in Lamps; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this speciiication, and to the letters and tigures of reference marked thereon.

Figure 1 of the drawings is a representation ot' a perspective View of a han ging lamp-frame, showing my invention applied; and Fig. 2 is a side view, partly in section, of a lamp and its attachments, illustrating my invention.

This invention relates to improvements in oil-lamps; and the nature of the invention consists in the combination, with the U -shaped support and a globe ring having the rodguides or sleeves attached to said support, of thelamp-ring havin g slide-rods, the upper ends of which work in the rod-guides or sleeves,

and the lower ends of which are surrounded by the exposed extension-springs, as will be hereinafter more fully set forth.

In the annexed drawings, the letter A desi gnates the base, upon which is erected the U- shaped upright B, the parts A and B constituting the frame of the lamp. The upright B has at its upper ends the parallel sleeves C, through which the rods D, which sustain the ring E, in which a lamp, F, is supported, are extended. The sleeves C are connected with the ring E, by means of the spiral springs G, that by their reaction hold the lamp up against ametallic ring, H, rigidly secured to the sleeves C aforesaid, upon which the globe I is secured by the usual means. The globe is thus stationary, while, by drawing down upon the lamp, the springs G yield and allow the wicktube a to appear below the globe, when it may be lighted without interfering in anyway therewith.

In the drawings the cleft burner bis shown attached to the globe-ring II; but this is not obligatory, as it may form a part of the lampbody. In this case the ring H will merely support the globe.

When the lamp is designed to be attached to a wall, a back plate, J, connected to the globe-rin g or to the sleeves C by arms, is used, and the base-plate is then dispensed with; but when the lamp is to be used indiscriminately as a Wall or table lamp it will have both the base and back plates, as shown in Fig. 2.

Figure 1 shows my invention applied to a swinging lamp. In this case the base and back plates are dispensed with, and the upright B of the frame is inverted, and provided with a ring or hook, d, at its upper or highest point, as a means of attachment to a supporting bracket, chain, cord, or other equivalent device. The remainder of the attachments are precisely as above set forth.

Itis evident that the lamp may be made stationary and the globe movable relative to the frame without changing the nature ot my invention.

In practice, the lamp-body is readily detachable from its ring, and is provided with proj ectin g spurs, that enter corresponding recesses in the said ring, for the purpose ot' holding the lamp steady and affording guides as to how the lamp should be placed in the ring in order that its wick-tube may enter the cleft burner when the latter is part ofthe globering.

What I claim as new, and desire to secure by Letters Patent, is-

The combination, with the U-shaped support B and the globe-ring H, having the sleeves C attached to said support, of the lamp-ring E, having the slide-rods D, the upper ends of which work in the sleeves C, and the lower ends of which are surrounded by the exposed extension-springs, as specied.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

FREDERICK RATCLIFF.
